Abstract

The invention relates to the field of environment-friendly composite materials, in particular to a biomass environment-friendly wood-replacing board. The biomass environment-friendly wood-replacing board is mainly made of natural fibers, the natural fibers and polymer resin are mixed and combined through a modifying agent, a solubilizer and other auxiliaries, a small amount of rubber powder is mainly added, a balance sea island structure phase diagram in a sub-micro phase state is formed by the whole system of the materials, a micro network structure is formed through interweaving, and the key technical problem that traditional similar materials are poor in tenacity and poor in nail holding ability is effectively solved. The manufactured biomass environment-friendly wood-replacing board has the advantages of being stable in dimension, resistant to abrasion and corrosion, capable of being nailed, sawed and riveted, waterproof, capable of preventing termites and being widely used, and the like.

Description

technical field [0001] The invention relates to the field of green composite materials, which is a kind of natural fiber as the main body, through the cooperation of modifiers, solubilizers and other auxiliary agents to make natural cellulose and polymer resin compatible and mixed, the main thing is to add A small amount of rubber powder makes the whole system of the material form a sub-microphase uniform sea-island structure phase diagram, and interweaves into a micro-network structure of biomass instead of wood green board, which effectively solves the problem of poor toughness and poor nail-holding force of similar materials in the past. The key to technology. The manufactured substitute wood green board is stable in size, not easy to deform or warp, wear-resistant, corrosion-resistant, nailable, sawable, rivetable, laminating, water-resistant, termite-proof, and widely used. technical background [0002] Since many countries have banned the logging of wood, scientific r...
